IMPROVEMENT IN PROPELLING- APPARATUS.

The Schedule referred to in these Letters Patent and making pert ofthesame.

Toall whom it may concern Be it known that I, CORNELIUS SCHILLING, ofthe city, county, and State of NewYork, have invented a new and improvedPropeller; and I do hereby declarethe following to be a full, clear, andexact description thereof, which will enable those skilled in the art tomake and use the same, reference being had to the accompanying drawingforming part of this specification, in which drawing Figure 1 representsa longitudinal vertical section of this invention.

Figure 2 is a plan or top view of the same.

Similar letters indicate corresponding parts.

This invention consists in the arrangement of a propeller-blade, whichis attached to a lever suspendcd from two rods, which are connected byan intermediate link, and one of which is attached to a crank, while theother is pivoted to a standard or bracket, in such a manner that, byimparting to said crank a revolviug motion, a compound oscillatingmotion is imparted to the propeller-blade, causing the same to dip downinto the water, swing forward, riseout of the water, and swing backward,and by these means a vessel can be propelled with ease and facility.

The propelling mechanism is mounted on a platform, to which a revolvingmotion can be impart-ed by a pinion mounted on an upright shaft, andgearing in a stationary segmental rack, in such a manner that, byturning the upright shaft, the direction in which the propellingmechanism acts can be changed at pleasure, and the vessel can be steeredwith ease and facility. A sliding keya'nd perforated disk serve to stopthe platform in the desired position.

In the drawing-- The letter A. designates a circular platform, which isfitted into cavity at or near the stern of a vessel, and which isretained in position by a center pin, a, so that it can be freelyrevolved in either direction.

Suitable fi-iction-rollers, b, inserted in the under surface of theplatform, facilitate the revolving motion of the same.

From this platform risetwo standards, B, which form the hearings for thecrank-shaft O, and from the crank 0 extends a rod, (1,130 the outer endof which is pivoted the level-D, carrying the propeller-blade e. p

' From the platform A also extends a bracket, E, from which extends arod,jc, to the propeller-lever D, said rod being pivoted at one end tothe bracket and at the opposite end to the lever, as shown in fig. 1

The rods (1 and c are connected by a link, 1; which tands parallel tothe lever D, and serves to sustain the rods (1 a in any position intowhich the same may be brought by the revolution of the crank 0.

By imparting a. revolving motion to the crank-shaft, the blade 0 assumesa compound oscillating motion, whereby the same is raised out of thewater, carried forward, then depressed and carried back in the direction opposite to that in which the vessel is to he propelled. Thisaction of the propeller-blade remains the same in whatever direction thecrank-shaft is turned, with that exception, that in every case thevessel is propelled in a direction opposite to that in which the blade 0is carried through the water, and this directionis reversed when themot-ion'oi' the crank-shaft is reversed.

In the platform A is secured an upright'shaft, It, on the lower end ofwhich is mounted a pinion, i, which gears in a segmental rack, j,fastened in'the circumference of the cavity of said platform, and to theupper end of the shaft It is secured a hand-wheel, It, as shown infig. 1. By turning this hand-wheel the platform, together witlrthepropelling mechanism, is rotated, and the direction in which thepropeller acts can thus be changed at pleasure. The

blade 0, therefore, acts as'propeller and also as the rudder.

Through the baud-wheel It extends a key, I, the lower end of which canbe made to catch in one'of the holes of a perforated disk, in, which issecured to or forms a portion, of the platform A. By means of this keythe platform can be locked in any desired posi tion, but if it isdesired to change the direction of the propeller, the key must be raisedand the hand-wheel revolved in the requisite direction.

This propeller is intended particularly for canalboats, but it can alsohe used with advantage for other vessels, and it can be driven by steamor any other suitable p'ower.

What I claim as new, and desire to secure by Letters Patent, is-

1. The lever I), carrying the blade e, and secured to rods d c, incombination with the link f, the crank c, and the'platform A,substantially as shown and described.

2. The pinion i and rack j, in combination with the platform A, rods (10', link 1, and lever D, carrying the blade a, substantially as setforth.

This specification signed by me this 25th day of June, 1870.
